* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): fix a panic during target discovery when `vmagent` runs with `-promscrape.dropOriginalLabels` command-line flag. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3580). The bug has been introduced in [v1.85.0](https://docs.victoriametrics.com/CHANGELOG.html#v1850).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): [dockerswarm_sd_configs](https://docs.victoriametrics.com/sd_configs.html#dockerswarm_sd_configs): properly encode `filters` field. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3579).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): fix possible resource leak after hot reload of the updated [consul_sd_configs](https://docs.victoriametrics.com/sd_configs.html#consul_sd_configs). See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3468).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): fix a panic in [gce_sd_configs](https://docs.victoriametrics.com/sd_configs.html#gce_sd_configs) when the discovered instance has zero labels. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3624). The issue has been introduced in [v1.85.0](https://docs.victoriametrics.com/CHANGELOG.html#v1850).

Previously random samples could be selected during querying.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): fix a panic during GCE service discovery for instance without any labels set. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3624).
